hello am in need of some help on question 7 and 11, if someone has time please also try question 15. i really don't have any idea how to do the following question, and i need to have this assignment in soon. could you please try. thank you

(7)
allows a user to put a maximum and minimum price and see all properties in that price range.

(11)
allows a user to see all properties with certain number of bedrooms or more

if you have time. but not important

(15)
allows a user to see all properties in a "similar" range - where "similar" is defined as the same number of bedroons and the same garden status (HINT overload ==);

Code tags added. -Narue

Don't post that much code without code tags, and don't bump your thread after just an hour. Both are incredibly rude and don't encourage people to help you.

so.... what are you having problems with? Are you getting any errors? Is it not giving the right values for something? Let us know what the problem is and we can try to help you

Please don't ask for help in a private message. I will be more than happy to help you if you just let us know what part of this assignment you are having a problem with... not just which assignment numbers then all of your code.

For assignment 7.) - it seems you need to implement a search function in your building class and hold the array index of each house within the price range in another array, then display them. Something like the following prototype with what I've described defining it:

building::searchPrice(int minPrice, int maxPrice)
{
//search for houses in the array
//display houses found
}

If you are still having problems with that, then show me the code you try for it and we'll see what we can work with.
